WILLIAM BARNETT JACKSON, OF NEWFI-ELD, PENNSYLVANIA.

To ulliuhom it may concern:

Be it known that I, WILLIAM BARNETT JAoKsoN, a citizen of the UnitedStates, and

lowingis a fu a resident. of Newfield in the county of Pot: ter andStateof Pennsylvania, have invented anew and 1m 'roved Chair, of which thefolfl, clear, and exact description; This invention relates to chairs.

The object of the invention is to produce a I chair of simpleconstruction, having improved means forlattaching the legs, back andbraces in' position; the general pur ose of the invention being toproduce a 0 air which will have in weight.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.- A Reference is to be had to the accompany mg drawings forming apart of this specification, in which similar characters of referenceindicate corresponding parts in all the figures.

Figure 1 is a perspective 'of a chair constructed according to myinvention; Fig. 2 is a vertical cross section throu h'the upper portionof the chair shown in ig. 1, a portion of one of the legs being brokenaway and shown in section; Fig. 3 is a horizontal cross section throughone of the legs and.illustrating the manner of mounting the bracestherein; and Fig. 4 is a vertical section through great strength though'light the chair seat and running in a direction from the front towardthe rear.

Referring more particularl to the parts, 1 represents the seat frame 0,a chair, which frame is preferably formed of sheet metal which isstamped so as to present a central opening 2 and a rounded edge orcurved :fiange 3extending com letely around the .'frame.- At the cornerso the frame 1, which frame is of substantially rectangular form, 1esockets 4 and 5 are provided on the under si e of theframe; These areformed'of suitable metal, and are secured in any suitable manner to theunder side of the flange 3. The sockets 4 are disposed at the front ofthe .chair, while the sockets 5 are dis osed at the rear, as indicated.These soc ets receive the up er extremities of the legs 6, and the sidesof the legs are provided with recesses 7 which receive. sockets 8 whichare substantially similar to, the sockets-4 and; 5 aforesaid. 'Thesockets 8 are disposed opposite to each other, as indicated and affordmeans Specification of Letters Patent.

said, while the sockets the sides an Patented Dec. 17, 1907.

for attaching horizontal braces or rungs 9 which connect the le s andbrace them in the usual manner. A On t e upper side of the seat frame 1and in alinement with the sockets 5, back .sockets 10 are provided, andthese sockets receivethe side bars 11 of the back, which are set thereinin the manner indicated.

Intermediately disposed between the sockets 10, I provide a plurality ofsockets. 12, which are of small size, and in these intermediate sockets,back slats 13 are received, which extend u wardly between the side bars11. The si e bars 11, together with the back slats 13, sup ort ahead-rest 14, which is provided on its ower edge with sockets 15 whichreceive the ends-of .the bars 11, and sockets 16 which receive the slats13. The sockets 15 are similar to the sockets 1O afore- 16 are similartothe sockets 12.

' The chair is provided with a bottom 17, of

cane or similar material, which is attached to the upper side-of theframe in any suitable manner.

A'chair constructed as described will be found to be very strong at thejoints, while at the same time it is inexpensive to manufacture and putto ether.

Attention is ca ed to the fact that the sockets 5 and 10 are inalinement with each other, so that a weight resting'upon the back willbe received b the frame 1 directly over the rear legs. This arrangementenables a frame of ve 10 ed, whic is very desirable. Attention is a socalled to the fact that the flange 3 does not only extend along thefront and sides of the chair, but also extends'across the rear edge. Therimary object of this flange on d frontis to prevent the forming of asharp edge, which might be uncomfort able to a person sitting inthe'chair, and it also improves the appearance of the chair. At therear, however, this flange performs an important function in stiffeningthe frame .90 A light construction to be emv transversely, so as to takeany strains which may come-upon the back between the rear 1e metal,formed with a rearwardly projecting base-flange 18, and it is to thisflange that the sockets 12 are attached- The up er edge and ends of therest are formed, a so,

into a rearwardl projecting flange '19 which v The head-rest 14 is madeout of sheet.

is rounded like t e flange 3 of the seat frame.

Having thus described my invention, I claim as new and desire tosecure-by Letters Patent:

- 1. A chair, consisting of a sheet metal seat frame having a downwardlycurved flange extending entirely arounddt and provided with a centralopening, a bottom secured to the frame over the opening thereof,sockets.

projecting from the under face of the frame at the front and rear andbetween the margin and the central opening, legs engaging the sockets ofthe frame and provided with socking the sockets of the head rest and thesockets on the upper face of-the seat frame.

2. A chair, comprising a seat frame, sock ets projecting from the underface of the seat frame at the front and rear, the sockets being at adistance from themargin-of the frame,

legs engaging the sockets of the frame and provided with socketsprojecting therefrom,

rungs engaging the leg sockets, sockets proj ectingfrom the upper faceof the seat frame at the rear thereo the end sockets being larger thanthe intermediate sockets and in alinement with the rear leg sockets, ahead rest rovided with sockets projecting downwar y from its lower edge,the endlsockets being larger than the intermediate sockets,

and side bars and slats engaging the sockets of the head rest and thesockets on the upper face of the seat frame.

' 3. A chair, comprising'a metal seat frame having a downwardly curvedflange extending entirely around it, sockets secured to the under faceof the seat frame at the front and rear, the sockets being at a distancefrom the margin of the frame, legs engaging the sockets of the seatframe and connected by rungs,

- sockets projecting from the upper face of the seat'frame at the rear,the end sockets, be-

ing larger than the intermediate sockets and in 'alinement with the rearleg sockets, a

metal head rest having a curved flange at its upper edge and ends and abase flange, sockets projecting downwardly from the base flange of thehead rest, the end sockets being larger than the intermediate sockets,and

side bars and slats engaging the sockets of the ead rest and the socketsonthe upper face of the seat frame. I

In-testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses".
